Title (EN) PROCESS FOR THE REMOVAL OF CORROSION METALS FROM CARBONYLATION CATALYST SOLUTIONS
(FR) PROCEDE PERMETTANT D'ELIMINER DES METAUX DE CORROSION DE SOLUTIONS DE CATALYSEUR DE CARBONYLATION
Abstract: front page image
(EN)A process for the removal of corrosion metal contaminants from a carbonylation catalyst solution comprising an iridium and/or rhodium carbonylation catalyst, an alkali and/or alkaline earth metal and corrosion metal contaminants in which the catalyst solution is contacted with a cation exchange resin having its active sites partially loaded with a sufficient amount of alkali and/or alkaline earth metal to maintain the concentration of said alkali and/or alkaline earth metal in the catalyst solution and recovering a catalyst solution of reduced corrosion metal contaminant content.
(FR)L'invention concerne un procédé permettant d'éliminer des contaminants métalliques de corrosion d'une solution de catalyseur de carbonylation comprenant un catalyseur de carbonylation à l'iridium et/ou rhodium, un métal alcalin et/ou des terres alcalines et des contaminants métalliques de corrosion. La solution de catalyseur est mise en contact avec une résine échangeuse de cations dont les sites actifs sont partiellement chargés d'une quantité suffisante de métal alcalin et/ou des terres alcalines afin de maintenir la concentration dudit métal alcalin et/ou des terres alcalines dans la solution catalyseur et de récupérer une solution de catalyseur à teneur réduite en contaminants métalliques de corrosion.
